Netflix engineers presented a centralized platform for managing data deletion across various storage systems while ensuring durability, availability, and correctness. The platform has successfully deleted 76.8 billion rows without data loss, addressing challenges like data resurrection and resource spikes during deletion. Key recommendations emphasize the importance of rigorous validation and centralized monitoring.

This article introduces a new framework for understanding consensus algorithms, focusing on distributed durability and high availability. It critiques traditional methods like Paxos and Raft, proposing flexible durability policies and goal-oriented rules that adapt to modern cloud environments.
